Scientist IV

Job Details

The Jet Propulsion Laboratory, California Institute of Technology, invites applications for a Staff Scientist position working in cosmology. JPL has an established culture for collaborations and opportunities for developing new ideas and pursuits and is committed to fostering an enriching and rewarding research environment with strong support and coaching for professional and personal development.

Responsibilities:

We are looking for an innovative Scientist IV to play a pivotal role in the analysis and interpretation of the next generation of dark sector surveys. As JPL expands its leadership in NASA's Nancy Grace Roman Space Telescope and ESA's Euclid, the focus is shifting from precision measurement to the complex challenges of modeling and cosmological interpretation. This role is essential for capitalizing on the imminent release of Euclid's ~1900 square degrees (Data Release 1) and the imminent launch of Roman.

The successful candidate will:

• Bridge the gap between raw measurement and theoretical insight, providing critical expertise in cosmological simulations, modeling, and interpretation of cosmological data.
• Join the vibrant JPL dark sector community contributing to the JPL-led OpenUniverse cosmological simulations project and the Euclid and Roman science teams. Beyond current missions, the successful candidate will join a collaborative team to shape the post-Roman landscape, developing mission concepts and strategies to influence the 2030 Decadal Survey.
• Integrate astrophysical, instrumental, and statistical systematics into robust models, which will aim to define the future of how we understand the dark universe.

Qualifications:

• A Ph.D. in Astrophysics or a related discipline with a minimum of 5 years' experience, or a Master's degree in a related discipline with a minimum of 7 years of related experience; or a Bachelor's degree in a related discipline with a minimum of 9 years of related experience.
• Deep technical foundation in some combination of cosmological simulations, modeling, and cosmological data interpretation.
• Proven expertise in weak lensing and/or galaxy clustering as primary probes for investigating dark matter and dark energy.
• Strong interpersonal skills and a demonstrated ability to thrive within a collaborative team environment.
• Excellent written and verbal communication skills and a proactive commitment to fostering diverse ideas and backgrounds in the workplace, ensuring a dynamic and inclusive research culture as we tackle the most complex questions in modern cosmology.

Preferred Skills:

• A Ph.D. in Astrophysics or a related discipline with a minimum of 5 years' experience.
• Demonstrated professional reputation as a productive researcher with a track record of publications in peer-reviewed journals and presentations at national and/or international conferences.
• Demonstrated record of successfully proposing for research funds as Principal Investigator.

Note: Complete applications will include a cover letter describing the applicant's vision for their role at JPL as a leader and contributor in the fields of dark energy cosmology and dark matter, a curriculum vita including a bibliography of peer-reviewed and other publications, a statement on research experience and research objectives, and contact information for at least three professional reference writers Applications received by May 15th, 2026, will receive full consideration.
